> Project: UIMA
> Issue Type: Bug
> Components: DUCC
> Reporter: Jerry Cwiklik
> Assignee: Jerry Cwiklik
> Priority: Major
> Fix For: 3.0.1-Ducc
>
>
> The pullservice synchronizes code in multiple places reducing overall
> throughput. Also, the code creates an instance of XStream when serializing
> and deserializing each task. This applies both to client (TAS) and the
> pullservice.
> Modify code to remove serialization and also create an instance of XStream
> service and pin it to each thread both in the client and the pullservice.
